I have a 27 year old 20x40x4 pool with a 1.5 hp Hayward Super Pump and an Lomart DE Filter that developed a slow leak I can't stop. Replacement parts no longer available. There are 30 ft of 1.5 inch tubing from the skimmer to the pump and 20 ft of 1.5 in return line. Pump is at pool water level. The old Lomart has 9 D.E. disk filters with a total surface area of 25 Sq. Ft. I am looking for an over sized D.E. filter replacement. Is the Pentair 180008 one of the better replacements? Can you sugge

Yes this Pentair filter would be a great replacement and considerable upgrade from you Lomart filter. If you go with this Pentair filter then you would also need to purchase the Pentair 1.5" mulitport valve. Thanks for the great question.

I have a 30 year old sylvan pool with 48 KDI de stainless filter and 6 way multiport americana valve. Please advise on filter and valve selection.

Hi Bob, You can go with the Pentair FNS Plus 48 Sq Ft Filter w/o Valve and you can use the 1.5" Threaded Multiport Valve for D.E Filters or the 2" Multiport Valve Threaded for D.E depending on your size plumbing.

I have a Pentair Filter Part # 180008 on the bottom of the tank is a plug that started to leak water i went to check it and it fell off what can I doe to fix this

A  Answered on 7/19/2015 by InyoPools Product Specialist Dennis R.

PG - I think you are referring to the drain plug at the botton of the tank. This plug should screw back in. If the plug's threads are stripped, here is a link the filter's parts list :Drain Plug (#24) and associated O-ring (#23). If the threads in the tank are stripped, you will have to buy a new tank bottom (#25) or a new filter.

I found the filter but can the shell be bought separately?

A  Answered on 9/8/2016 by InyoPools Product Specialist Scott W.

The top and bottom tank are sold separately. Part numbers 4600-0017 and 4600-0021.
